Mollisia on Typha

Hi to all


These small (0.3-0.6 mm) gregarious, sessile, not really cupulate apothecia were found on Typha old leaves at 1350 m of altitude. The excipulum is brownish black and they have not conspicuous marginal elements. Any crystal we have seen in medulla or excipulum. The ascomata are KOH yellowish. Ascospores strongly clavate with well visible gel sheath around fresh discharged ascospores.


It seems to be close to Mollisia hydrophila that I found regulary on Phragmites at the sea level, but this species are paler ascomata with many crystals.


Have you any idea for help me?


 


Thanks again

Re : Mollisia on Typha
It reminds me a bit of Scutomollisia lanceata (clavate spores, KOH-yellow reaction) but that species has 1-septate spores in the living asci.

M. juncina is paler and has smaller spores, also I noted KOH-.

Hi Zotto


You are right because the ascomata are very close to Scutomollisia lanceata. The ascospores are also sub-cuneate but lack the septa. Maybe it could be an Scutomollisia.


Thanks
